PAPER-MAKERS FELT.

SPECIFICATION forming part of Letters Patent No. 431,112, dated July 1,1890. Application filed July 3, 1889. SerialNu. 316,461. (No specimens.)

To all whom it may concern:

Be it known that I, DUNCAN M. FULLERJL citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Paper-Makers Felts, ofwhich the following is a specification.

This invention relates to felts for papermakers use; and it consists ofa woolen fabric woven in tubular or endless form, having theloosely-twisted threads woven in as warp and the hard-twisted threads asthe filling, the object being the production of a papermakers felthaving the fabric shrunk or fulled transversely from that of formermakes.

The particular advantage of this felt is a seamless endless fabric notliable to shrink crosswise of the felt and become narrowed up in apaper-making machine.

The method of carrying out my invention is as follows: I take for thewarp the threads having the less turns of twist to the inch and theharder-twisted threads for the weft or filling in my arrangement of thematerial for the loomthat is, I place the threads having the less turnsin twist in the loom for the warp and feed the harder-twisted threadswith the shuttle in the process of weaving my fabric. I thus make afabric which in fulling will shrink more in the direction of the warpthan in the direction of the filling. I next out from this tubular ordouble fabric a portion sufficiently long for one felt. The length thuscut constitutes the width of my felt, having a raw edge without aselvage. This edge I finish by binding, hemming, blanket-stitching, orcrocheting, which, when the felt is finished by fullinggmakes an edgeequal to a selvage. This makes an endless felt without a uniting seam,and may be made of any length or dimensions required.

Having described my invention, I claim As a new article of manufacture,a papermakers felt consisting of a fabric woven in tubular or endlessform, having the looselytwisted threads woven in as warp and thehard-twisted threads as the filling, 11aving edges finished and thefabric shrunk or f ulled, substantially in the manner described.
